Process Evaluation (Research Question 4): The goal of the process evaluation is to understand how facility processes and reminders affect the sustainability of healthcare aide uptake of the innovation. We will examine how the reminders are implemented and perceived by participants, as well as how healthcare aides providing peer reminders are identified, received by their peers and supported by their supervisors. This data will gathered using observations, questionnaires and interviews. Observations: Anytime research staff enter a study facility, they will be alert to observe responses of facility staff or clients to the reminder interventions. Upon exiting the facilities, they will record fieldnotes. Research staff will be instructed to include only general information in their fieldnotes, and not include information that would identify specific site staff or clients. Educators' fieldnotes will be useful for understanding processes of and responses to coaching the healthcare aides that provide reminders. Questionnaire: We will survey a licensed practical nurse and a manager from each facility using a questionnaire to elicit perceptions of the reminders. Interviews-Healthcare Aides: To understand healthcare aides' views of the reminders we will use interviews rather than written questionnaires, as many healthcare aides speak English as a second language. We will interview approximately 6 healthcare aides from purposively sampled facilities until we achieve saturation. Four facilities (2 positive & 2 negative extreme cases; one from each arm) will be sampled based on facility assessments. Interviews-Peer Reminders: To understand the peer reminder experience we will interview approximately 6 healthcare aides providing peer reminders from each high intensity reminder arm until saturation is achieved.
